Definitions

  • the distal portion of the endoscope shaft 126 includes a distal working channel portion 170' that is re-configurable between a first smaller cross-section as shown in FIG. 7A for accommodating fluid outflows and a second larger cross-section as shown in FIG. 7B for accommodating a tool 188 introduced through the working channel 170 and its distal portion 170'.
  • the sensor diagonal dimension DD is greater than 50% of the shaft diameter SD or greater than 60% of the shaft diameter.
  • the working channel diameter WCD is greater than 30% of the shaft diameter, greater than 40% of the shaft diameter or greater than 50% of the shaft diameter.
  • the working channel portion 170' in the distal end is adjustable between a first cross-sectional dimension and a second cross-section dimension.
  • the working channel portion 170' in the distal region of the endoscope shaft 126 is adjustable between a partially constricted shapes and a non- constricted shape.
  • the physician can easily insert the distal end 425 of a tool 188 into the mouth of the large diameter recess R without any risk of contacting the non-sterile handle portion 120. Thereafter, the physician can move the tool distal end 425 distally over the surface 428 of the recess R and into and through the port 172 of the working channel 170. By using this method, the physician can be assured that the tool 188 will not contact the non-sterile field 420.

Abstract

L'invention concerne un endoscope comprenant une tige ayant des extrémités proximale et distale et un axe longitudinal entre celles-ci. Une poignée est couplée à l'extrémité proximale de la tige et un capteur d'image est porté sur l'extrémité distale de la tige. Un canal s'étend à travers au moins une partie de tige distale et a un diamètre de canal, et une section du canal est reconfigurable entre une forme rétrécie et une forme non rétrécie pour recevoir des outils introduits à travers celle-ci. La dimension diagonale et le diamètre de canal combinés sont généralement supérieurs au diamètre de tige externe. Le capteur d'image peut être connecté à un connecteur sur le boîtier par un premier circuit souple de relâchement et une source de lumière sur la tige peut être connectée à un connecteur sur le boîtier par un second circuit souple de relâchement.
